Membralox® Ceramic Membranes and Modules

Pall Membralox ceramic membranes are asymmetric
multi-channel membranes composed of a porous alumina
support and a filtering layer (alumina, zirconia, titania).

High compactness of the multichannel membrane
combined with high permeability allows the treatment of
large volumes with high throughput.

The Membralox GP ceramic membranes range with
longitudinal permeability gradient, ensure an homogeneous
and calibrated flux along the flow channel, thus optimum
utilization of membrane surface within a stable micro filtration
regime.

Widest Separation Range

The exceptional structure of Membralox filtering elements
has enabled the development of the widest range of micro and
ultrafiltration ceramic membranes.  A complete range of
modules helps for scale-up from laboratory separations to full
size industrial needs.

Cost Effective Separations

The superior characteristics of Pall Membralox ceramic
membranes provide economical solutions for high added
value macro-molecule concentration, effluent recycling or
reduction and difficult fluid clarification.

Membralox filtration modules are the key element in process
reliability.

Pall Membralox Membranes Quality

  • Unique ceramic support of the 12 µm pore size
    allows the highest flux.
  • Patented alumina end-sealing provides superior
    resistance to corrosion and cleaning cycles.
  • High homogeneity and quality of the filtration layers
    for optimum filtration performances and selectivity.
  • Exceptional mechanical resistance for long service life.

 

1 The membranes based on high purity alumia are certified for
use in contact with food fluids by Commission Directive 2005/31/EC.
All membrane components are made from materials that our suppliers
state meet the requirements for food contact use: Alumina and titania
are GRAS, Zirconia layers on alumia support are limited in 21 CFR
Sect. 177.2910.

The limits of use of Membralox modules are determined mainly by the
type of housing or gasket materials employed.  Based on valuable pilot
test data, our Scientific and Laboratory Services can provide advice in
selecting the best membrane and module configuration to match your
process requirements.
